Safety:

Most accidents that occur during machine operation and maintenance are caused by failure to observe basic safety rules and precautions. Before operating your machine or performing maintenance, read and become familiar with all the safety precautions and recommendations given in this section.

• Remember that failure to observe even a single pre- caution could involve you and the people around the machine in a serious accident.
• Foreseeing potential dangers is vital for preventing accidents. All personnel working with the machine, including the supervisor, machine operator and oiler, should be sensitive to potentially dangerous situations and take the necessary measures to prevent accidents.
• Safety precautions and recommendations are outlined in this section and are also included in the operation and maintenance instructions given in subsequent sections. Warning labels are also provided on the machine.

Foreword:

• This service manual describes the composition of the Model TR-150XL-4 rough terrain crane, its repair, checks
  and adjustment methods and other relevant matters. Note that this service manual does not provide the
  information in the separate service manuals given below.
• This service manual applies to the cranes with the specification numbers given below. Check the specification
  number on the nameplate of your crane.
• Read the separate operation and maintenance manual and the parts catalog for repair and maintenance of the
  crane in conjunction with this manual. If the parts needs to be replaced, check the disassemble units and sales
  units in the parts catalog before replacing them.
